How the conversion works
Multiply by 334.5525656 to go from megapascal to foot of water column, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? foot of water column to megapascal — 1 ft H₂O = 0.0029890669 MPa.
